System for communication from a user to the publisher of a scannable label

ABSTRACT

“Publishers” generate individual QR codes which may be either displayed on a smartphone or printed on a physical label, and “consumers” scan and decode those codes for secure and private communication with the publishers, without either party knowing the phone number or email address of the other party. At least one profile associated with the publisher is an anonymous profile that permits the disclosure of only a specified subset of the otherwise available information about that publisher, and that information is not directly embodied in the displayed code, but rather is stored on a secure remote server which is selectively accessible by the consumer. If both parties have not authorized the release of their respective names and phone numbers (or other public contact information) to the other party by exchanging respective public profiles within a predetermined time period, any associated temporary contact numbers are disabled and all anonymous contact information is deleted from the remote server. A remote app on the publisher&#39;s smartphone may be used to generate the QR code and upload the associated contact information and permissions to the secure server, and a local app on the consumer&#39;s smartphone may be used to scan and process the QR code and commence secure and private communication with that publisher via the secure server.

FIELD OF THE INVENTION

The present invention relates generally to exchange of privateinformation over a public network, and more particularly to a system forpublishing and using scannable labels for facilitating privatecommunications with a remote business or individual.

BACKGROUND ART

A QR (“Quick Response”) code is a machine-readable optical label thattypically contains (or is linked to) information about the item to whichit is attached. It differs from a conventional UPC barcode label in thatthe encoded information is presented in two dimensions using apredetermined encoding mode such as numeric, alphanumeric, binary, orcharacter (eg kanji) and an associated error correcting code to storeand reconstruct the data, and offers more reliable readability andgreater storage capacity. Applications include product tracking, itemidentification, time tracking, document management, and generalmarketing.

A QR code consists of a two dimensional array of binary valued cells(typically either black or white square dots arranged in a square grid),which can be captured by an imaging device (such as a digital camera ina smart phone) and processed to reconstruct an approximation of theoriginal two dimensional pattern of dots. Some of the cells have fixedvalues arranged in a fixed pattern and define the size and orientationof the grid, and other cells represent bits of encoded binary dataarranged in rows and columns of the square grid. The associated errorcorrecting code is then used to extract the original data from thehorizontal and vertical components of the reconstructed square grid.

The amount of data depends on the size (number of discrete data points)of the label and the complexity (robustness) of the associated errorcorrecting code:

-   -   Level L—up to 7% damage    -   Level M—up to 15% damage    -   Level Q—up to 25% damage    -   Level H—up to 30% damage

FIG. 1 specifies the data that may be encoded with a 40-L (maximumcapacity) QR Code.

Unlike the older, one-dimensional barcodes that were designed to betraversed by a narrow beam of light, a QR code is captured by a2-dimensional digital image sensor and the resultant digital image datathen analyzed by a programmed processor. The processor locates the threedistinctive squares at the corners of the QR code image, using a smallersquare (or multiple squares) near the fourth corner to normalize theimage for size, orientation, and angle of viewing. The small dotsthroughout the QR code are then converted to binary numbers andvalidated with an error-correcting code.

Although initially designed for tracking parts in vehicle manufacturing,QR codes now are used in a much broader context, including bothcommercial tracking applications and convenience-oriented applicationsaimed at mobile-phone users (termed mobile tagging). QR codes may beused to display text to the user, to add a vCard contact to the user'sdevice, to open a Uniform Resource Identifier (URI), or to compose ane-mail or text message. Various QR code apps are available that can beused for publishing (generating and printing) a new QR code and forusing (capturing and interpreting) a previously published QR Code.Japan's NTT DoCoMo has established de facto standards for the encodingof URIs, contact information, and several other data types. Theopen-source “ZXing” project maintains a list of QR code data types.

QR codes have been used over a wide range of applications, includingcommercial tracking, entertainment and transport ticketing,product/loyalty marketing and in-store product labeling. Many of theseapplications target mobile-phone users (via mobile tagging). Users mayreceive text, add a vCard contact to their device, open a URI, orcompose an e-mail or text message after scanning QR codes. They cangenerate and print their own QR codes for others to scan and use byvisiting one of several pay or free QR code-generating sites or apps.Recruiters have placed QR codes in job advertisements, while applicantshave placed their own QR code in their CVs and visiting cards. QR codescan also be used in accessing personal information for use byorganizations.

Typically, a smartphone having a built in digital camera and a built inQR scanning app functions as a QR code scanner and extracts (andoptionally displays) the encoded digital data in its original format(numeric, alphanumeric, binary, or character). A special user app(typically downloaded from or otherwise in communication with the samewebsite that created and published that particular QR code) converts thedecoded digital data into some useful digital format (such as a standardURL for a website), thereby obviating the need for a user to type theencoded data into a web browser or other user app. Such a QR coderepresentation of a brand's URL has become a focus of advertisingstrategy, since it provides a way to access a brand's website morequickly than by manually entering the individual characters comprisingthe URL and any associated search parameters.

QR codes storing addresses and URLs may appear in magazines, on signs,on buses, on business cards, or on almost any object about which usersmight want information. Users with a camera phone equipped with thecorrect reader application can scan the image of the QR code to displaytext, contact information, connect to a wireless network, or open a webpage in the phone's browser. This act of linking from physical worldobjects is termed hardlinking or object hyperlinking. QR codes also maybe linked to a location to track where a code has been scanned. Eitherthe application that scans the QR code retrieves the geo information byusing GPS and cell tower triangulation (aGPS) or the URL data encoded inthe QR code itself is associated with a location.

QR codes can be used with various mobile device operating systems tosupport URL redirection, which allows the QR codes to input metadata toexisting applications on the device. Many paid or free apps areavailable with the ability to scan the codes, extract the embeddedmetadata, and hard-link to an external URL.

QR codes can be also used to establish a secure log in to an associateddevice: a QR Code is shown on the login page on a computer screen, andwhen a registered user scans that code with a verified smartphone, thatuser will automatically be logged in on the computer. Authentication isperformed by the user's smartphone which uses the information in QR codeto contact the responsible authentication server and execute theappropriate authentication protocol.

The amount of data that can be stored in the QR code symbol depends onthe datatype (mode, or input character set), version (1 through 40,indicating the overall dimensions of the symbol), and error correctionlevel (Low=7%, Medium=15%, Quality=25%, or High=30%). The maximumstorage capacities occur for 40-L symbols (version 40, error correctionlevel L), as set forth in FIG. 1.

US Patent Publication 2014/0032285 describes a system in which scanninga QR code generates an email address to a payment gateway. US PatentPublication 2014/0117087, describes a system for using QR codes in adating service.

SUMMARY

In accordance with one aspect of the present invention, a business owner(or other responsible individual) dealing with external customers (orother unrelated individuals) is able to validate and correlate orders,offers, reviews and/or suggestions from a customer (or other unrelatedindividual) by means of an encoded label that is physically associatedwith a particular time, location, activity, and/or transactionassociated with an interaction between the business and the unrelatedindividual, and that may be used by any such unrelated individual toinitiate and/or validate a private and/or anonymous communication withthe business owner in a manner that allows the business owner to managehis business and improve its service without any direct confrontationwith that particular customer.

In accordance with another aspect of the present inventions, a firstindividual seeking to establish a relationship (either personal orprofessional) with other individuals is able to initiate limitedcommunication with those other individuals by means of an encoded labelthat is physically associated with the first individual, but that doesnot include any private information (such as email addresses or Facebookpages) that the first individual does not want to disclose to strangers.The encoded label may then be used by another individual to establish aprivate and/or anonymous communication with the first individual.

In a presently preferred embodiment, a “publisher” desiring to maintainprivate and anonymous communications with customers or casualacquaintances or other unrelated individuals (“consumers”) must firstdownload a remote app that generates QR codes specific to the publisherwhich may be either displayed as individual digital images on asmartphone or other interactive display device in the physicalpossession of the publisher or printed on a physical label which isaccessible to the particular consumers of interest to that publisher, Ineither case, the consumers are also required to install a local app(which can be the same as (or part of a subset of) the downloaded remoteapp) on their devices in order to scan and decode the displayed orprinted QR code and commence secure and private communication with thepublisher via a remote server.

The publisher's remote app preferably includes a first means forreceiving contact information and other private details relating to eachof the publisher's profiles, a second means for generating a uniqueidentification code (and associated QR code symbol) for each specifiedprofile, a third means for publishing the QR code symbol for each uniquecode if and when instructed to do so by the publisher, and a fourthmeans for transmitting to a secure remote server the unique code and anyrelated details for each of the publisher's profiles.

The consumer's local app (or if the consumer is also a publisher, thelocal app portion of his remote app) preferably includes a first meansfor enabling the consumer's interactive device to scan a digital imageof the publisher's displayed QR code symbol, a second means forprocessing that digital image to recover the embedded uniqueidentification code, and a third means for transmitting the recoveredunique identification code and any relevant details of the consumer'sprofile to the secure remote server.

A table is preferably maintained by the remote app for storingpreviously received transactional codes and the corresponding contactand transactional details for the specific profile which each coderepresents, including any later received updates and/or deletionsthereof.

In a first exemplary specific embodiment, in response to thetransactional code derived from a particular QR code and anyaccompanying message received from a particular consumer, the remoteserver sends a text message or email (or other private communication) tothe individual or business who published that QR code without revealingto that publisher the text address (mobile phone number) or emailaddress or any other private information associated with the consumerwho scanned that QR code. By this means, the consumer can send ananonymous text message, email, or other message (and/or can forward thataccompanying message) to the owner or management of a business, withouteither party knowing the phone number or email address (or other contactinformation) of the other party.

In a second exemplary specific embodiment, a unique QR code is generatedby the remote app for each individual “publisher” (or if a particularpublisher wishes to maintain different public and/or anonymous profilesfor different categories of acquaintances, for each profile maintainedby that publisher) by means of the remote app. Upon scanning andinterpretation of the published code for a particular “profile” andtransmittal of that code to the secure server, the remote apps ofunrelated “consumers” have access only to certain information about aparticular publisher that has been uploaded to the secure server by thatpublisher's remote app, linked to the particular profile associated withthat particular published code, and marked as “disclose”. For example,the information stored on the secure server may include first name, lastname, phone number, address, email, Identification and/or Driver'sLicense number, social security number, and photo, but the informationdisclosed to the unrelated consumer will be limited to first name,photo, and a numerical code which may be used to send a limited numberof text messages as defined by the “anonymous” profile that correspondsto the particular code that was displayed by the publisher and wasscanned by the consumer.

In both of these specific embodiments, at least some (and preferablyall) of the stored information about a particular business or individualresponsible for publishing the QR code is not directly embodied in thecode, but rather is stored on the remote app or on the same secureremote server which is selectively accessible by the local apps of therespective parties.

An enhanced log be maintained at the secure remote server for storingeach instance of a received transactional code together with the time oftransmission to the remote app and any other transactional detailsassociated with that transmission, whereby suspicious transmissions froma particular user or user device for transmission to another particularuser or user device may be identified and appropriate action may beperformed after a specified number of such communications have beenreceived.

In a presently preferred embodiment, an individual or a business orother group of affiliated individuals (the “publisher”) desiring tomaintain private and/or anonymous communications with customers or otherunrelated individuals (the “consumer”) must first download a remote appthat generates two dimensional QR codes specific to that publisher whichmay be either displayed on an interactive display device (such as aSmartPhone) or printed on a physical label, whereby a specific QR codeassociated with that particular publisher may be selectively displayedto one or more consumers of interest to that publisher. Once aparticular consumer has already installed a local app (which can be thesame as the downloaded remote app) on his interactive display device, hemay scan and decode the displayed or printed code and use that decodedinformation to commence communication (preferably anonymous) with thepublisher, optionally including details (such as time, transaction,and/or location) associated with its display by the publisher and itsscanning by the consumer.

In a first exemplary specific embodiment, the local app instructs theremote app to send a text message or email to the individual or businesswho published the code but did not make public the text address (mobilephone number) or email address of the publisher. By this means, acustomer (the consumer) can send a private text message, email, ormessage to the owner or management of a business (the publisher),without either party knowing the phone number or email address of theother party.

In a second exemplary specific embodiment, the publisher's remote appgenerates and displays (publishes) the publisher's QR code (or aselected QR code if the publisher has more than one “profile”) prior tothe the publisher's display device being scanned by a particularconsumer's interactive display device by means of a local app (which maybe the same as the remote app). Preferably, at least one profileassociated with the publisher is an anonymous profile that permits thedisclosure of only a specified subset of the otherwise availableinformation about that publisher. For example, the known informationabout the publisher may include first name, last name, phone number,address, email, Identification and/or Driver's License number, socialsecurity number, and photo, but the specified information disclosed tothe unrelated consumer scanning the QR code associated with such ananonymous profile might be limited to first name, photo, and a temporarycontact number which may be used to send a limited number of textmessages during a limited time to the particular publisher.

In both of these specific embodiments, most (and preferably all) of theknown information about a particular business or individual responsiblefor publishing the code is preferably not directly embodied in thedisplayed code, but rather is stored on the secure remote server whichmay be selectively accessible by the consumer's local app once thatparticular consumer has been given the appropriate permission. This istrue even if the coded label uses a relatively high capacity twodimensional format such as a QR code.

In a further refinement of the invention, at least some informationabout the consumer is also stored on the secure remote server in amanner analogous to that of the publisher (preferably using the sameremote app functionality), whereby the consumer may selectivelyauthorize access to his information by, and/or direct communicationfrom, the publisher who initiated the contact with the consumer. In yetanother refinement, if both parties have not authorized the release oftheir respective names and phone numbers (or other public contactinformation) to the other party within a predetermined time period, anyassociated temporary contact numbers are disabled and all associatedinformation is deleted from the remote server.

BRIEF DESCRIPTION OF DRAWINGS

FIG. 1 specifies the data that may be encoded with a 40-L (maximumcapacity) QR Code.

FIGS. 2 through 25 are screen shots showing a typical operationalsequence that may be performed by a presently preferred embodiment ofthe invention.

DETAILED DESCRIPTION

A presently preferred embodiment combining aspects of the previouslydescribed embodiments is shown in FIGS. 2 though 25. FIGS. 2 and 3represent the first page that comes up on the publisher's screen, whichasks him to allow (“OK”) push notifications. Then it is followed by thelogin screen (FIG. 3), by entering the user's “Email” and “Password”,(default at top of screen), or by linking to Facebook, Twitter, orGooglePlus, using respective buttons at bottom of screen.

FIG. 4 shows the different QR profiles the user has created, including 3default profiles that the app comes with. When the user selects (clickson) one of these saved profiles, a correspondingly labeled QR codeappears (FIG. 5) on the publisher's screen whereby it may be scanned bythe other user (eg, a customer) (See also FIG. 14).

FIG. 6 shows how a saved profile may be deleted. To delete a profile,simply slide (iOS) and tap (iOS) or hold (Android) Delete. Then confirmthat you want to delete it.

FIGS. 7 and 8 show how a new profile may be created by simply clickingthe +(add) icon on the top right on the home page, and then selectingthe profile type (Personal or Professional).

FIGS. 9 and 10 show the available information fields for a PERSONALprofile (“John” in the illustrated example); FIGS. 11, 12 and 13 showthe available information fields for a PROFESSIONAL profile (“JohnLawyer” in the illustrated example).

After the publisher's selected QR code appears on his screen (FIG. 14),the publisher can show it to another user (the “consumer”) with a localapp which has a Scan QR mode which scans it when the customer places hisphone's camera above the QR code displayed on the publisher's screen.Once the consumer (eg, a potential customer at a trade show) has therebysuccessfully scanned the displayed QR code, a box (FIG. 15) appears onhis screen, which allows him enter a description (optional) and save theassociated contact code and any optional description as a new anonymouscontact (FIG. 16).

After that other user clicks “OK”, an “added successfully” message isdisplayed on his screen (FIG. 17), which verifies that the publisher'scontact info (as defined in the particular profile which created thatparticular QR code) has been added successfully to the customer'sContacts.

To edit his QR profile, the user simply goes to his “My QR Codes” tab(FIG. 18) and clicks Edit on whichever profile he want to edit,whereupon the previously stored information for that profile (FIGS. 19and 20) Is displayed. This will allow you to edit any of the fields ofthe selected profile. When finished editing, click “Save”, and theprofile(s) will be updated.

To see your contacts, click on the “Contacts” tab (FIG. 21). Thecontacts are displayed by group in the following order: Personalprofiles first (in alphabetical order), then Professional profiles (inalphabetical order), and then Anonymous profiles (in alphabeticalorder). If there is no name associated with the QR code you havescanned, then that profile goes on top displaying any description youmay have entered, which is why the contact “Business” is before “Bob”.You may email, text, or call your contacts by clicking the correspondingicons, but only if that contact has shared that information with you.

As shown in FIG. 22, you may also see (and possibly edit) theinformation your contacts have shared with you by clicking on theprofile icon (FIG. 21) for that contact.

FIG. 23 shows the “Settings” page, where users can invite friends viaemail, text, Facebook, Twitter, or GooglePlus; view any Notifications(see below); see the relevant “Terms and Conditions”, “Privacy Policy”,and/or About” pages, or Log Out.

FIG. 24 shows a blank Notifications page. A user receives notificationswhen he has scanned someone, someone has scanned him, when an anonymouschat message is waiting, when an anonymous contact is about to expire orwhen it has expired, and also when the system or the systemadministrator chooses to send any information relevant to a particularuser or group of users. Since in the illustrated example, there are nonotifications, the Notification screen says “You have no notificationsat this time”. If there were notifications, it would display them andhave a time and date next to each. User receives notifications when hehas scanned someone, someone has scanned him, when someone has sent ananonymous chat message and is waiting, when an anonymous contact isabout to expire or when it has expired, and also when the system or thesystem administrator chooses to send any information relevant to aparticular user or group of users.

As shown in FIG. 25, a user with an Anonymous profile can decide thenumber of days someone can keep in contact with him, through a secureserver, using that particular anonymous profile. Choices are 1 day, 3days, 7 days, 15 days, or 30 days.

All confidential user data is preferably stored in the secure server andnot in the client. In some environments, such as Android and the Picasaimage server, images such as Profile pictures and QR codes) may besecurely cached in the client side.

It is required for a second person to have the app in order to scan a QRcode, call/text/email one of his/her contacts, and visit any of his/hercontacts' Facebook/Twitter/LinkedIn/Instagram.

An 8 digit random code is preferably generated for each profile createdby any user. No private data is encoded into the QR Code. If someoneuses another application to scan the QRCode, all they would get is an 8digit random code that must be decoded after it is received by thesecure server.

Each profile is associated with a QR Code. If a user has two profiles,he has 2 QR Codes associated with them. The number of codes has norelation with the number of contacts of a user. For example, a user, say“personA”, has 50 contacts and 2 profiles for himself. He has 2 QRCodes(one for each profile). The contacts are linked through the internaluser IDs of the app. So if “personA” has 50 people in his contacts, inthe contacts table his userID is linked to 50 other user IDs.

The passwords are preferably encrypted using a MD5# algorithm (Thisencryption cannot be decrypted, only compared). All other data is storedas such. If 2 parties are exchanging messages they do it through aconversation ID which links their user IDs. Chat Messages that userssend to each other are stored in a messages Table in the server. Othermessages like SMS(Text) messages are stored in a standard way in thephones.

Those skilled in the art will realize that although the invention hasbeen described with reference to a specific coding format (a highcapacity 40-L QR code), many of the underlying concepts are usable withother known and not yet known scannable code formats, and the inventionis not necessarily limited to encoded data that are embodied in knownscannable codes such as one dimensional UPC barcodes or two dimensionalQR codes.
